The Purple Banded, Yellow Spotted Snortlesnuffle (PBYSS for short) – in anti-cam mode!

When it is is camouflage mode it is entirely invisible against any yellow/purple/green/white/black patterned colours – in fact against anything that looks exactly like it – which isn’t much! – This explains why there are so few of them left!
They spawn by looking at themselves in the mirror, and since there are so few mirrors in their native habitat of earthquake-prone rock quarries, this also goes some ways to explaining their rarity.
